显示面板的修补线路及其修补方法 Display panel repair line and repair method thereof

技术领域Technical field

本发明是有关于一种显示面板的修补线路及其修补方法，且特别是有关于一种用于改善信号线的电阻电容延迟(RC-delay)的显示面板的修补线路及其修补方法。 The present invention relates to a repair line for a display panel and a repair method thereof, and more particularly to a repair line for a display panel for improving resistance-capacitance delay (RC-delay) of a signal line and a repair method thereof.

背景技术Background technique

图1为现有液晶显示面板修补信号线的示意图。如第1图所示，一液晶显示面板包含有一基板10，于基板10上具有若干条扫描线12及若干条信号线14，并且所述若干条扫描线12彼此平行且与所述若干条信号线14交错。所述扫描线12以及所述信号线14之间形成若干个画素区域，并各透过一薄膜晶体管(Thin Film Transistor, TFT)(未图示)控制画素的更新。另外，于基板10上还具有一扫描芯片22及若干个信号芯片24，于图式中为清楚说明仅以一个信号芯片24表示。所述扫描芯片22用于依序的驱动所述扫描线12、所述信号芯片24是用于提供画素的显示信号给所述信号线14。FIG. 1 is a schematic diagram of a repair signal line of a conventional liquid crystal display panel. As shown in FIG. 1, a liquid crystal display panel includes a substrate 10 having a plurality of scan lines 12 and a plurality of signal lines 14 on the substrate 10, and the plurality of scan lines 12 are parallel to each other and to the plurality of signals. Lines 14 are staggered. A plurality of pixel regions are formed between the scan line 12 and the signal line 14 and are each transmitted through a thin film transistor (Thin Film Transistor, TFT) (not shown) controls the update of pixels. In addition, a scan chip 22 and a plurality of signal chips 24 are further disposed on the substrate 10. As shown in the drawings, only one signal chip 24 is shown. The scan chip 22 is used to sequentially drive the scan line 12, and the signal chip 24 is a display signal for providing a pixel to the signal line 14.

由于画素数量的提高，在基板10上的相邻的扫描线12或是相邻信号线14之间仅有数微米的间隔。因此在制作过程中，可能会因为异物（例如尘埃）造成信号线14断开。为解决信号线14断开的问题，现有的液晶显示面板还会在基板10上设置用于修补断开信号线的修补线(rescue line)16。修补线16设置于该些扫描线12及信号线14所形成的显示区域11***，并与若干信号线14交错并间隔一绝缘层。当某一信号线14发生断开的情形时，修补线16可利用与该信号线14重迭处（以黑点表示）进行激光焊接(laser welding)以修复信号线14断开的后半部。而信号芯片24所提供的显示信号则通过修补线16经由路径162来向断开的信号线14提供信号。Due to the increase in the number of pixels, there are only a few micrometers of spacing between adjacent scan lines 12 or adjacent signal lines 14 on substrate 10. Therefore, during the manufacturing process, the signal line 14 may be broken due to foreign matter such as dust. In order to solve the problem that the signal line 14 is disconnected, the existing liquid crystal display panel is also provided with a repairing line for repairing the disconnected signal line on the substrate 10. Line) 16. The repairing line 16 is disposed on the periphery of the display area 11 formed by the scanning lines 12 and the signal lines 14, and is interlaced with a plurality of signal lines 14 and spaced apart by an insulating layer. When a certain signal line 14 is broken, the repairing line 16 can be laser welded by using the overlapping of the signal line 14 (indicated by black dots) (laser) Welding) to repair the second half of the signal line 14 disconnected. The display signal provided by the signal chip 24 is then supplied to the broken signal line 14 via the repair line 16 via the path 162.

请参照图1及图2A，图2A为图1中A、B点的未修正的显示信号图。比较图1在同一水平线上的A、B两点：因为在A点的信号线14断开，故需要通过修补线16走路径162来传递显示信号至A点；而在B点的信号线14正常无断线，故信号直接走路经142由上往下传递。随着面板尺寸日渐增加，扫描线12及信号线14的数量越来越庞大，使得经由路径162传递至A点较经由路径142传递至B点长，并且有较大的电阻电容延迟(RC-delay)。因此A点较B点的显示信号失真的较为严重。然而，当显示信号差异太大时会导致在A点的充电率(charging ratio)较B点小很多，而在A点附近有弱线(weak line)的状况产生。Please refer to FIG. 1 and FIG. 2A. FIG. 2A is an uncorrected display signal diagram of points A and B in FIG. Comparing Figure 1 with two points A and B on the same horizontal line: since the signal line 14 at point A is broken, it is necessary to pass the path 162 through the repair line 16 to transmit the display signal to point A; and the signal line 14 at point B. Normally there is no disconnection, so the signal walks directly through 142 from top to bottom. As the panel size increases, the number of scan lines 12 and signal lines 14 becomes larger and larger, so that the transfer to path A via path 162 is longer than the transfer to point B via path 142, and there is a large resistance-capacitance delay (RC- Delay). Therefore, the display signal at point A is more severe than the display signal at point B. However, when the display signal difference is too large, it will cause the charging rate at point A (charging Ratio) is much smaller than point B, and there is a weak line near point A.

请参照图1及图2B，图2B为图1中A、B点的修正后的显示信号图，其中A点及B点的显示信号分别以以虚线及实线表示。在现有技术中，通常会在修补线16上设置一缓冲放大器(buffer amplifier)20电路以改善A点信号线的RC-delay情况，如图2B所示。同时也可解决A点附近弱线的问题。Please refer to FIG. 1 and FIG. 2B. FIG. 2B is a modified display signal diagram of points A and B in FIG. 1, wherein the display signals of points A and B are indicated by broken lines and solid lines, respectively. In the prior art, a buffer amplifier (buffer) is usually disposed on the repair line 16. Amplifier) 20 circuit to improve the RC-delay condition of the A-point signal line, as shown in Figure 2B. At the same time, it can also solve the problem of weak lines near point A.

然而，请参照图1及图3，图3为图1中C、D点的显示信号图，其中C点及D点的显示信号分别以实线及虚线表示。比较图1在同一水平线上的C、D两点：C点位于信号线14开路处的前段，而D点所处的信号线14正常，因此C点的RC-delay会较D点处小很多，当显示信号差异太大时，在C点附近也会有弱线（与D点所处之信号线差异过大）的状况产生。However, please refer to FIG. 1 and FIG. 3. FIG. 3 is a display signal diagram of points C and D in FIG. 1, wherein the display signals of points C and D are respectively indicated by solid lines and broken lines. Comparing Figure 1 with two points C and D on the same horizontal line: Point C is located at the front of the signal line 14 at the open end, and the signal line 14 at point D is normal, so the RC-delay at point C will be much smaller than the point D. When the difference in display signal is too large, there will be a weak line near the point C (the signal line difference from the point D is too large).
